Cannot iterate over subkeys in NTUSER.DAT\Software

[Khyrenz Ltd]

This fails for the user NTUSER.DAT hive in Win 11 image available at https://www.khyrenz.com/resources:

#!/bin/python

import sys
from regipy.registry import RegistryHive

#Getting argument = NTUSER.DAT file - successful
reg = RegistryHive(sys.argv[1])

#This correctly gets subkeys under NTUSER\Software
for sk in reg.get_key('Software').iter_subkeys():
print(sk.name)
#This fails to find any subkeys under Software (e.g. Microsoft) despite above list showing keys exist
for subk in reg.get_key('Software\'+sk.name).iter_subkeys():
print(subk.name)
